Second Jap in Shanghai Jail Ends His Life SHANGHAI, China, April 25 (AP) – Maj. Chozo Matsuo, former legal adviser to the Japanese military governor of Formosa, hanged himself last night in his jail cell, using a noose fashioned from strips of torn clothing. Matsuo was the second Japanese to end his life there within a week. Five days ago Gen. Rikichi Keedo, top Japanese commander on Formosa, died from taking poison. American war crimes officers said they had obtained statements from Matsuo implicating him as one of the Japanese responsible for the sham court trial and execution of 14 American flyers forced down in Formosa last June. Matsuo commanded the firing squad. Matsuo and a dozen other Japanese were brought to Shanghai from Japan two weeks ago to face war crimes trials. Three Doomed to Die HONGKONG, China, April 25, (AP) – Three Japanese soldiers were sentenced to death today in Hongkong’s first war crimes trial, convicted of the vengeful torture and killing of nine Chinese villagers after Japan had agreed to surrender. Nine subordinates were sentenced to prison terms ranging from two to 10 years.
